IMPROVEMENT IN CORN-SHELLERSL Specification'forming part of LettersPatent No. 1'72, [71, dated January 11, 1876; application filed April 6,1874.

To all whom it may concern:

Be it known that I, WILLIAM S. REEDER, of St. Louis, St. Louis county,Missouri, have invented a certain new and useful Improvement inOorn-Shellers, of which the following is a specification: I

The class of corn-shellers to which my im- V provement applies is knownas cylinder cornshellers; and my improvement relates to the manner ofsupporting the barred concave in the side pieces of the machine; andconsists in forming grooves in the side plates for the reception of thesegmental end plates of the concave, (the wrought-iron bars or gratebeing connected by the said segmental end bars into which the grate-barsare cast.)

Heretofore the concave has been held in place by lugs or ribs castuponthe inner face of the side plates, and projecting therefrom. Theseprojections have been found to interfere with the efficient working ofthe machine, because the said lugs o'r ribs formed impediments to theears in their passage through the machine, and tothe shelled corn inescaping between the bars of the concave. The segmentalend bars of theconcave also formed a ledge, on which the shelled corn collccted,andthis deposit prevented, to some extent, the proper operation of themachine.

These difliculties are overcome by my improvement, in which grooves orchannels are cast in the side plates, which grooves are madesufficiently deep to receive the whole thickness of the end or segmentalbars of the concave, so that the exposed faces of the same are justflush with the inner faces of the side plates, and consequently there isno projection to check the passage of the ears or cobs between thecylinder and concave, or the passage of the shelled corn through thelatter.

In the drawings, Figure 1 is a perspective View, showing my invention.Fig. 2 shows the position of the bar in the groove by transversesection.

The case of the machine has side plates A A and ends B. In the sides arecast curved channels or grooves G, in the form of the arc of a circle,so that the curved end bars E of the concave may be inserted endwiseinto the open end 0 of the grooves, and each section of the concavepushed forward to form the whole concave, as shown, the end sectionresting against the ends ofthe grooves at of. This arrangement admits ofthe easy insertion and removal of the concave without taking the machineapart. F F are the bars of the concave. The bars F F are of wroughtmetal, and

are cast into the curved bars E E.

Nothing is broadly claimed as new in the manner of sliding the sectionalconcave into or out of the machine, as this has been practicedheretofore; but the novelty of my improvement consists in the provisionof the channels or grooves 0, cast in the side plates, and of sufficientdepth to receive the whole of the segmental bars E, so that the exposedface of the said bars is flush with the inner face a, of the sides A,resulting in leaving no impediment to the free passage of the ears ofcorn, the shelled corn, or the cobs, as set forth, the

shelli ng-surface of the concave extending all' across from side toside.

I claim as my invention- The segmental bars E and bars F of the concave,in combination with the plates A A, having open-topped grooves orchannels 0 (J, said grooves being of such a depth that the face of thebars E will be flush with the inner face of the plates, substantially asand for the purpose set forth.
